Figure 3-12 ABM-P in Uni-directional Mode Using one Core
3.3.1
In Uni-directional applications, the ABM-P can be programmed to make a minimum
header translation. This is necessary in a Mini-Switch configuration as both the forward
and backward direction of a connection traverse the devices in the same direction. The
OAM functions in the Infineon ALP (PXB 4350) or AOP (PXB 4340) devices need the
same LCI for forward and backward direction of a connection.
This is clarified by the example shown in
from PHY
connected. The terminal sends ATM cells with this identifier and expects cells in the
backward direction from PHY
direction translates VPI/VCI
the upstream direction. Similarly, for the backward connection from PHY
ALP receives ATM cells from PHY
